Question
I have recently planted "Lavender Lady" and "True Lavender", the former of which is sprouting excellently, if not ahead of schedule, but gets to a point of approx 2" stem, the leaves split down the center and it wilts away. The latter is taking far longer, to date I've noted 2 sprouts. Both are grown indoors approx 75 degrees, and in a tinted window that gets 3hrs direct evening sun. I keep soil moist, but not overly so.  Once 2" I repotted 1 each into those brown disintegrating containers and am using Miracle Gro Potting Mix.

How do I get the "Lady" to continue and the "True" to take? I live in S. Florida so I've accepted the indoor window box as an option.

Answer
Hi Jena,
Thanx for your question.  I don't three hours of direct sunlight from a window is enough.  When I grow lavender from seed, I have my pots under 40-watt flourescent shop-lights and the seedlings get at least 10 hours a day during initial growth.  I never have a problem with them.  If you have covered the pot with clear plastic, take it off to inhibit damping off disease which could be causing the wilting.  Also, the tinted window may be screening out part of the sun spectrum which would cause growth problems for the seedlings.  So, you are not going to grow the lavender outdoors but as a potted plant indoors?  I don't know how well that will work because the lavender your describe I believe are lavender that need to go dormant for the winter in order ot store energy for bloom and growth for next year.  This is a resting period.  Spanish (l. stoechas) and French (l. dentata)are lavenders that can be grown outdoors in South Florida with the Spanish being more easily grown in hot, humid climates.  Both lavenders are beautiful, with the great lavender scent, bushy growth habit, hardy, etc.  All you have to do with them is trim them up when they get too bushy.  I have grown both lavenders from seed even though they have to be grown as annuals here in the Midwest, where I live.  If you don't have frost, place the seedlings outdoors in a place that is protected from direct sunlight and rain.  Make sure you keep them watered but not soggy.  AFter 10 days, they can go in direct sunlight.  YOu will have better luck than using a window sill with tinted glass.  I hope this helps.
